Subject: [net 09/12] net/mlx5: Fix flow counters SF bulk query len

From: Avihai Horon <avihaih@...dia.com>

When doing a flow counters bulk query, the number of counters to query
must be aligned to 4. Current SF bulk query len is not aligned to 4,
which leads to an error when trying to query more than 4 counters.

Fix it by aligning SF bulk query len to 4.
